In the last 4 years of creating 3D cups, I’ve used both polymer clay and air-dry clay. While both are popular modeling material, there are differences. I've learned that some crafters may think that polymer clay is scary to use so let’s break down the differences and talk about some of the pros of both! I promise either way both are fun and easy to use and maybe by the end of this you’ll try something new!
What is Air-Dry Clay?
Air-dry clay is a soft clay that dries/ hardens when exposed to air. It dries at room temperature and depending on the thickness of the sculpt it can take 24-72 hours to dry. It is a great option for children or beginner crafters due to being easy to shape. It is also Non-Toxic! While it does come in a variety of colors, most crafters paint the clay after its done drying. Air-dry clay tends to be a little more fragile, especially thinner pieces compared to polymer clay. It is also not waterproof. While being able to dry by air is a bonus, air-dry clay needs to remain moist to be able to work with it.
What is Polymer Clay?
Polymer Clay is a modeling clay that remains in a soft, flexible state until baked in the oven. Once it’s baked, it cures and begins to harden. Polymer clay is also Non-Toxic so no need to worry about baking in the oven! When I first began making 3D cups, I wanted to try polymer clay so bad, but the oven part was what concerned me. Once I sat down and researched polymer clay and learned that there aren’t harmful chemicals involved, it changed the way I sculpted completely because it gave me more free range! So, I can completely relate to those of you who are nervous about stepping into something new!
As stated previously polymer clay needs to be baked to cure/ harden. Each pack of Sculpey clay contains instructions on the pack. Make sure to follow them! Once the clay has baked not only does it become hard but also waterproof! It has a smooth finish and comes in a variety of colors, which is my favorite part! Most times I skip the “painting” stage, but you can paint polymer clay too!
I hope that learning more about the differences and pros of both air-dry and polymer clay helps you in your clay journey! Have fun and be sure to tag @Sculpey with all your creations!
